Caspian and Aral Seas. Infrared satellite image of the Caspian Sea (at centre) and Aral Sea (at upper right). In the infrared range deep water is black,shallow water is blue,bare ground is grey,green vegetation is red and clouds are white. The Seas lose water only by evaporation. The use of water from their feed rivers for irrigation caused the seas to shrink,leading to environmental and economic problems. Schemes designed to save water and redirect it to the Caspian Sea have lead to it increasing in size. These schemes were carried out at the expense of the Aral sea,which continues to shrink.
